The R63 ECO Halogen halogen reflector bulb rated 42 W — the equivalent of a 60 W incandescent — casts a directed beam of warm white light (2700 K) with perfect colour rendering (CRI 100). Its Ø 63 mm reflector concentrates the light for accenting: pictures, shelves, worktops.
Standard E27 base: it screws in place of the old bulb with no modification and is fully dimmable with any standard dimmer. Halogen technology: instant light, ≈2000 h life and 30% savings versus incandescent.
